User guide/instructions-manual for Iphone SE 3rd gen exclusively?!

Would be smart to know before you start reading about for example a function of the camera on a iphone ios 16 if it was for your model, SE 3rd gen in my case. But the guide i was refered to is to general https://books.apple.com/se/book/iphone-anv%C3%A4ndarhandbok/id6443225518?l=en-GB

so you dont know before you read if it actually applies for you

; so i need help with anwsers to .1 is there a iphone SE 3rd gen instructions guide/manual of functions??

.2 before you change the title or feel confused about what im asking here, read again and do so slowly
